SIGNAL.

Specification of Letters Patent.

Patented Feb. 13, 1917.

Application filed May 31, 1916. Serial'No, 100,960.

To all whom it may concerm Be it known that I, GEORGE J. PAULY, a citizen of the United States, and resident of Frackville, in-the county of Schuylkill, State of Pennsylvania, have invented certain new and useful Improvements in Signals, of which the following is a specification.

My invention relates to an audible signaling apparatus to be used in mines. More specifically the invention comprehends an apparatus to be used in connection with lifts, cars, buckets, etc., that are used for lowering and hoisting miners into and out of the mine. I

The main object of the present invention is to provide a signaling apparatus of the above mentioned character which may be operated from the mine car, etc., to warn the engineer who is lowering the same that the persons in the car, etc., are in danger.

A further object of the invention is to provide a cable which is used for lowering and raising conveyances of the above mentioned type having electricity conductors embedded therein that are connected with the audible signal.

Another object of this invention is to utilize the cable as an insulator for the electricity conductors as well as to raise and lower the conveyances.

A still further object of the invention is to provide a novel mounting for the audible signal and the electric batteries whereby they can be easily reached, and where the signal may be easily heard by the engineer.

An additional object of the invention is to provide a signaling apparatus of the above mentioned character which can be applied to any mine conveyance, that consists of few parts, is inexpensive'to manufacture, and which may be placed on the market at a comparatively low cost.

\Vith the above and other objects in View which will become apparent from the following specification taken in connection with the accompanying drawing, the invention consists of the constructions,combinations and arrangement of parts which will be hereinafter set forth in detail.

On the drawings,

Figure 1 is a longitudinal sectional view through a drum having my invention ap plied thereto.

Fig. 2 is a view looking down on the top of the drum, the door being shown in dotted lines in an open position.

. Fig. 3 is' a side view of the drum and showing diagrammatically the electricity conductors connected with the circuit closer.

Fig. 4 is a view of the mine car and track upon which it travels; and r Fig. 5 is a view of. a portion of the cable showing the electricity conductors projecting from one end thereof.

The numeral 5 designates supporting hearings in which is mounted. a shaft 6. Rotatably mounted upon this shaft is a drum 7 for raising and lowering the mine conveyance, 8 that may be of any preferred type, but is shown in this instance as a car. i This drum 7 is rotated by any desirable means.

A conventional track-way is. shown at 9 which extends from the surface of the mineto the bottom thereof and upon which the car 8 travels.

Connected to the car 8 is a cable 10 which is also secured to the drum 7 and is adapted to be wound therearound. Arranged in this cable 10 are wires or electricity conductors 11 which are connected with any desirable circuit closer 12 which is shown in this instance as a push button and is mounted in a casing 13 on the car 8.

.Formed in one side of the drum 5 is an opening 14 and normally closing this opening is a door 15 which is supported by the hinges 17. A keeper 18 is carried by the door 15 and normally retains the same in closed position.

One end of the cable 10 is extended through an opening in the drum 7 and seated in a longitudinal recess 19.

Supported on the door 15 is a battery 20 which is in circuit with the wires 11 of the cable 10. Also supported upon the door 15 is an audible signal 21 which may be a bell, buzzer or the like. This signal is also in circuit with the wires 11 and the source of electrical energy 20. It will be seen that by mounting the battery and signal in the above manner, they are not subjected to-the weather and that by simply opening the door 15, access may be had to them without any difliculty.

From the foregoing disclosure, it is ob vious that by simply pressing the push button 12, the engineer is warned that the miners in the car 8 are in danger.

While I have disclosed the preferred emarranged in the interior of the drum, and 10 bodiment of my invention, I desire it unmeans for operating the signal. derstood that the same is susceptible of 2. In a signal, a drum having an opening various modifications and alterations that therein, a door closing the opening, a source 5 may fairly fall Within the scope of the apof electrical energy mounted upon the door,

pended claims. an electrical signal also mounted upon the 15 What is claimed is: door and in circuit with the electrical energy. 1. In a signal, a drum having an opening therein, a door closing the opening, a signal GEORGE J. PAULY.
